According to Mook random sampling is necessary when a researcher wants to apply his or her findings directly to a population.
What is random sampling?Each sample has an equal chance of being picked as part of the sampling procedure known as random sampling. A randomly selected sample is intended to provide a fair reflection of the entire population.Random sampling makes sure that the findings you get from your sample should be close to what you would have gotten if you measured the complete population. All the units in the population have an identical probability of being chosen using the simplest random sample.There are five different kinds of sampling: convenience, cluster, random, systematic, and stratified. It is comparable to picking some names from a hat after placing everyone's names in it. In the population, each component has an equal probability of appearing.To learn more about random sampling refer to:

consider simple diffusion (sd), facilitated diffusion (fd) and active transport (at) across a membrane. which process requires a concentration gradient of the transported molecule%?)
Considering simple diffusion FD and AT process requires a concentration gradient of the transported molecule%
Facilitated diffusion is the diffusion of solutes through delivery proteins in the plasma membrane. Facilitated diffusion is a kind of passive delivery.
Even though facilitated diffusion involves delivery proteins, it's far still passive transport because the solute is transferring down the concentration gradient.
In facilitated delivery, membrane proteins assist the diffusion of materials thru the cellular membrane. The protein binds the molecule being transported at the floor of the membrane, then passes it to indoors proteins that usually shape a channel or pore in the membrane.

homo habilis displays a great deal of variability some scientists think that larger homo habilis fossils with wider faces and bigger teeth should be classified in their own species called
This cranium has a wider, flatter face, a larger brain, and larger teeth than other Homo habilis fossils, prompting some scientists to name it Homo rudolfensis.
The word habilis is based on a Latin word meaning 'handy' or 'skilful'. This species is known as "handy man" because stone tools were discovered near its fossil remains, and it is assumed that this species developed the ability to shape stone into tools. The following year, parts of a boy's skeleton were discovered at the site, and additional fossils from other people were discovered. Their brain size, hand and foot features, and evidence that they may have used stone tools all suggested that a new type of human ancestor had been discovered.
Their brain size, hand and foot features, and evidence that they may have utilised stone tools all suggested that a new type of human ancestor had been discovered.

Explain the theory of plate tectonics and how they have changed Earth’s surface over time. Include the role of plate tectonics in the creation of landforms.
-Please include in your response:
- Identify the evidence for plate movement.
- Explain the different types of plate boundaries and what happens at each plate boundary in the creation of landforms over time.
Answer:
Plate tectonics is the theory that Earth's outer layer is composed of a number of large, rigid plates that move relative to one another. The movement of these plates is responsible for the creation of landforms and the shaping of Earth's surface over time.
There is a lot of evidence for the movement of these plates. For example, the distribution of earthquakes and volcanoes around the world is consistent with the movement of plates. In addition, the way that the rocks on the Earth's surface are arranged and the way that they have been deformed over time also provide evidence for the movement of plates.
There are three main types of plate boundaries: convergent boundaries, where two plates are moving toward each other; divergent boundaries, where two plates are moving away from each other; and transform boundaries, where two plates are sliding past each other.
At a convergent boundary, one plate will usually be pushed beneath the other, a process known as subduction. This can lead to the creation of mountain ranges, as well as the formation of volcanoes.
At a divergent boundary, the plates are moving away from each other, which can create gaps in the Earth's crust. This can result in the formation of new crust, as well as the creation of features such as rift valleys and mid-ocean ridges.
At a transform boundary, the plates are moving past each other, which can cause earthquakes and the formation of faults. This type of boundary is often associated with the creation of strike-slip faults, where the ground on either side of the fault is moving in opposite directions.
Overall, the theory of plate tectonics helps us to understand how the Earth's surface has changed over time and how landforms are created. The movement of the plates is a slow process, but it is ultimately responsible for the shaping of Earth's surface and the creation of the landforms that we see today.

Mike has heard about commercial laboratories that can compare segments of your DNA to those of people with common hereditary diseases in order to give you some idea of how susceptible you are to the diseases. The results of these types of tests are highly inconclusive. If Mike’s DNA showed that he shares similarities in a segment of DNA with people who have a given disease, his chances of developing that disease or passing it on to his children may be slightly elevated, but they are not 100 percent.

Describe how the availability of these genetic tests might affect the frequency of genetic diseases in individuals and populations.
Answer:
It is understandable why Mike would be interested in understanding his genetic makeup and potential health risks. However, genetic tests are highly inconclusive and are not covered by many insurance companies, so the decision to undergo testing is a personal one with potential risks and benefits. Pros of having such tests done include gaining a better understanding of one's genetic makeup and potential health risks, as well as being able to pass on this knowledge to future generations. On the other hand, cons of having such tests done include the high cost and lack of accuracy of the tests, as well as the potential for psychological distress caused by the results. The availability of these genetic tests could affect the frequency of genetic diseases in individuals and populations. More accurate tests could lead to earlier diagnosis and treatment of genetic diseases, potentially allowing for better health outcomes for those affected. Additionally, these tests could lead to better management of genetic diseases in populations by providing more accurate data on the prevalence of genetic diseases.

Natural selection affects the entire organism; the individual is the unit of selection. NS is unable to affect specific alleles (genes). The phenotype, not the genotype, is the unit of natural selection. However, it has the potential to alter genotype. Because an organism's phenotype is what interacts with its environment, natural selection focuses on it.
